I would consider that world shattering. It would suggest significant flaws in our understanding of the universe which would be very exciting.

Honestly i can't think of a more earth shattering discovery. It would be on par with aliens landing and saying we come in peace.

Obviously.

The earth shattering part is if quantum physics goes from an accurate description of most of the universe to one that isn't.

What you are basically saying is any theory could be wrong. Well duh, but that describes literally all earth shattering scientific discoveries.
